TITLE: Propagation of ion cyclotron waves in a plasma
PERIODICAL: Zhurnal tekhnicheskoy fiziki, v. 31, no. 2, 1961, 254-255
TEXT: The experiments were made by means of a device similar to that des-
cribed in Ref. 1. Gas discharge took place in a 1.6 m long glass tube with
a diameter of 60 mm, in an axially magnetic field with a field intensity
of up to 15 kilooerstleds. The magnetic field attained its maximum value
within 10- 2 see, it dropped by 2.7 times within 8.10-2 see. Hydrogen in
the pressure range from 10-4 to 10- 2 mm Rg serv-d as working gas. The
high-frequency energy was fed into the plasma by means of an induction
coil usually used in cyclotron heating. It consisted of six parts
connected in phase opposition. The axial periodicity of the h.f. magnetic
field in the coil was 16 cm,. The load current circuit consisting of this
coil and vacuum condensers had the quality factor 310. The current circuit

was fed by an h.f. generator with quartz stabilization and a power of 80 kw.
The duration of pulses varied between jo-5 and 10-2 sec, the working
frequency of the enerator varied from 5 to 30 Mcps. The absorption of the
h.f. power by tile plasma in the region of ion-cyclotron resonance was
determined by measuring the voltage in the current circuit as well as from
the change of the electron density durin6 discharge, and from the intensity
of the hydrogen spectral line Hp. With given parameters of the h.f.
current circuit about 5 kw were introduced into the plasma in the region
of ion-cyclotror. resonance. Owin6 to the resulting high degree of ioniza-
tion of the gas no -,;lasma formation by direct electrode discharge was
necessary. In this case, experiments could be made also at low hydrogen
pressures (up to 2.10-4 mm, Hg . The upper curve ~n Fig. 1 shows the
Change of load of the h.f. current circuit in the region of ion-cyclotron

resultsobtained prove the Penetration of.h.f. energy into the plasma in the'
form of ion-oyolotron waves. -The mentioned data also prove the results of
the experiments 'of T. Stike at al. in the stellarators:B-65 (v-65) and

TITLE: Study of the electrodeless discharge in a magnetic trap with

PERIODICAL: Zhurnal tekhnicheskoy fiziki, v. 31, no. 2, 1961, 255-258
TEXT: The plasma can be heated by a fast magnetic trap. In such a system,
the diameter of the plasma cylinder is shortened during compression, which
leads to a loo3er conre,,:tion between coil and plasma in experiments of
plasma heating by means of ion-cyclotron resonance. The presence of an
initial map-netic field HI may prevent a strong shortening of the radius of
the plasma cylinder without changing the degree of compression. Experi-
ments were iaade w4th the fleld Ej to obtain a hollow piasma cylinder and to
explain the interaction between the plasma and such a system of megnetic
fields. The authors a130 zjtudied gamma radiation which almost always
accomp-%nies &-,;.ch di3charg-_,s. The discharge of two condenser batteries
caused the formatinn of a three-Fhase field with the voltage Eq, = 30 v/cm?

the direction of drift is reversed. The same holds for the hydrogen
plasma- X-rodiation was 2tudied under the following conditions: 1) Anti-
parallel connection of coils without occurrence of gamma radiation;
parallel connection of coils in the presence of Hj; under these
conditions gamma radiation had an energy of about 50 kev and a mean inten-
sity of 2C mr/discharge. Gamma radiation was oIrserved in argon in the
pres3ure rang.-e P = 5-10- 5-10-3 mm H,~r and in h~rdrogen at

means of a le.;d --ollimator the author shows that radiation in the region

of the minimum of the magnetic field occurs between the mirrors. With
ET2 a 3 v/om no gamma radiation occurs independently of the other condi-
tions; 3) parallel connection of the coils in the presence of 1~- The
presence of H? changes the character of gamma radiation; the energy in- !
creases up to abbut 100 kev;.the pressure region in which gamma radiation
is formed is dhifted to the high-vaouum, by one order of magnitude; with
increasing H1 gamma radiation occurs every half period beginning with the
formation Of the plasma. The intensity of gamma radiation increases and
amounts to approximately 2-5 r/discharge. The photography of discharge in~
X-rays shows that the emission from the rod has its origin in the region i
between the mirrors. The glass tube which is inserted parallel to the rod,
at a distance of 1 cm reduces radiation intensity by 7-10 times. Fig. 3,v~
shows the oscillograms of radiation and the field Hz in the presence of H1.

The principal conclusions am that in the case of strong shoc% waves
the distr.:~'-_,zion of the conductivity behind the front of the shock wave cannot
detemined with the aid of this procedure, inasmuch as the half-width of the
cxiductivity zone behir&the front of the shock wave greatly decreases with in-
creasir4 Mach number, In the case of the work of Shao at al, this procedure can
bra US;d, but the results must be approached with caution, since only the eddy
cur--ents were taken into account and tharmal diamagnetism was completely ignored.

TEXTt The linear accelerator discussed here is the injector of the protok
synchrotron of the 01fal. It furnishes a atrong flux of accelirated
particles in short pulses. The pulses are separated by--relatively long
intervals of time. The resonator, containing screening tubes, excites
standing waves. It needs only a relatively small r-f-power ind it allows of
synchronizing several generators feeding the accelerator. Simultaneous .
phase stability and radial stability of the accelerated bunch is achieved
with the screening tubes and nets. The injection energy is 6C0 kov and the
synchronous phase 200. The generator wave length is 215 cm, the perioda-cf-

the accelerator have the length Lk . CPk T, where T - A/c, and the mean
effective field strength in all the gaps of the resonator is 19.9 kv/cM.
The phase focusing effect is accompanied by radial defocusing. The critical
phase pa max lies. between 540 and 710; in the present case, ;p 8 max >2TO. The.
utilization factor of the current injected ahould'be increased by inserting
a clyetron-type buncher between injector and injecting accelerator. During
one period of the r-f oscillations, the energies absorbed by a particle of
phase ? and by the synchronous particle are different. The first term of
the final particle energy at the accelerator output is the enerEy calculated,
and the second term is the deviation from it. The relative energy spread
is 0-3-10-2 in the case considered here. Supplementary investigations are
necessary to determine the spread in energy'due to radial oscillations; in
particular, the way the accelerating field Ez depends on the radius must be
studied. The capture angle calculated for ye 0 200 has a minimum at (p - 30P.
Currents of less than 10 me have but little effect on capture dvring
acceleration. Furthermore, the effect of the space charge on the radial
stability of the accelerator discussed here is insignificant. The angle of

TEXTs A type of accelerator combining the advantages of cyclic and linear
accelerators is discussed. It is a linetar accelerator bent to a tonclosed
ring or another non-closed curve. The accererated particles are kept in
their trajectories of constant or variable.radius by a magnetic field.
Ranial and axial stability is attained in the way customary for cyclic
accelerators. Phase stability can be achieved using the dependence of the.
revolution period of the accelerated particles on their frequency. High
energies can be attained in systems of large radius and comparatively
moderate field strength (-j1 kgauas for I Bev). The condition of phase
stability 822 a eV u)2N2kA where is the frequency of the phase

The frequency of the generator can be kept constant by varying.the
structural period of the linear accelerator. The advantages of such
accelerators are simplicity of injecting and extracting particles, con-
siderable increase of the beam current, constancy of the generator frequency
and of the magnetic field strength. The energy gained per revolution is of
the same order of magnitude as the total energy. 'The magnetic field is a
function.of radius and angle. When the quasistationarity condition
